This is a 'transit visibility zone.' Aliens living in it might be able to see us.

For centuries, human beings have looked at the night sky, hoping to see aliens.

Now, a group of scientists is trying to find out where aliens would have to be in order to see us.

Researchers from universities in the U.K. and Germany have identified nine planets that are "ideally placed" for their resident astronomers to detect Earth using the same methods Earth stargazers use to detect them, according to a new paper published in the Monthly Notices of the Royal Astronomical Society.


The astronomers looked for planets on which observers could view Earth's transit across the sun — the period where, from their perspective, our planet moves in front of its home star, causing it to dim slightly.

The study builds on the work of astrophysicist Rene Heller, who proposed the idea that intelligent extraterrestrial life located in these "transit visibility zones" might already know about Earth in a paper published last year in the journal Astrobiology.

"We've expanded on this by including all of the solar system planets and looking at the known and expected exoplanets in these regions," study lead author Robert Wells, a Queen's University Belfast Ph.D. student, says.

The work was made possible by the revival of the Kepler space telescope, which malfunctioned and was nearly left for dead in 2013.

Instead, engineers used sunlight pressure to stabilize the stellar eye later that year. It has since discovered more than 500 exoplanets — joining the more than 2,300 total detected in the telescope's eight-year run.

The next challenge? Finding where ET might actually be listening for that call.

None of the planets identified in the paper have the conditions to support life. The researchers expect to discover more worlds in the prime Earth-viewing zone in the coming months.

"Our hope is to find some planets which are potentially habitable and can see transits of Earth, which I think will be the best targets for SETI," Wells says.

Here's hoping when do we track our galactic neighbors down, they're not the kind we need Will Smith to deal with.

(Thankfully, we have Will Smith — just in case.)

On an old episode of "The Oprah Winfrey Show" in July 1992, Oprah put her audience through a social experiment that puts racism in a new light. Despite being nearly two decades old, it's as relevant today as ever.

She split the audience members into two groups based on their eye color. Those with brown eyes were given preferential treatment by getting to cut the line and given refreshments while they waited to be seated. Those with blue eyes were made to put on a green collar and wait in a crowd for two hours.

Staff were instructed to be extra polite to brown-eyed people and to discriminate against blue-eyed people. Her guest for that day's show was diversity expert Jane Elliott, who helped set up the experiment and played along, explaining that brown-eyed people were smarter than blue-eyed people.

Watch the video to see how this experiment plays out.

Cadbury has removed the words from its Dairy Milk chocolate bars in the U.K. to draw attention to a serious issue, senior loneliness.

On September 4, Cadbury released the limited-edition candy bars in supermarkets and for every one sold, the candy giant will donate 30p (37 cents) to Age UK, an organization dedicated to improving the quality of life for the elderly.

Cadbury was prompted to help the organization after it was revealed that 225,000 elderly people in the UK often go an entire week without speaking to another person.

Well Being

Young people today are facing what seems to be greater exposure to complex issues like mental health, bullying, and youth violence. As a result, teachers are required to be well-versed in far more than school curriculum to ensure students are prepared to face the world inside and outside of the classroom. Acting as more than teachers, but also mentors, counselors, and cheerleaders, they must be equipped with practical and relevant resources to help their students navigate some of the more complicated social issues – though access to such tools isn't always guaranteed.

Take Dr. Jackie Sanderlin, for example, who's worked in the education system for over 25 years, and as a teacher for seven. Entering the profession, she didn't anticipate how much influence a student's home life could affect her classroom, including "students who lived in foster homes" and "lacked parental support."

Valerie Anglemyer, a middle school teacher with more than 13 years of experience, says it can be difficult to create engaging course work that's applicable to the challenges students face. "I think that sometimes, teachers don't know where to begin. Teachers are always looking for ways to make learning in their classrooms more relevant."

So what resources do teachers turn to in an increasingly fractured world? "Joining a professional learning network that supports and challenges thinking is one of the most impactful things that a teacher can do to support their own learning," Anglemyer says.

A new program for teachers that offers this network along with other resources is the WE Teachers Program, an initiative developed by Walgreens in partnership with ME to WE and Mental Health America. WE Teachers provides tools and resources, at no cost to teachers, looking for guidance around the social issues related to poverty, youth violence, mental health, bullying, and diversity and inclusion. Through online modules and trainings as well as a digital community, these resources help them address the critical issues their students face.

Jessica Mauritzen, a high school Spanish teacher, credits a network of support for providing her with new opportunities to enrich the learning experience for her students. "This past year was a year of awakening for me and through support… I realized that I was able to teach in a way that built up our community, our school, and our students, and supported them to become young leaders," she says.

With the new WE Teachers program, teachers can learn to identify the tough issues affecting their students, secure the tools needed to address them in a supportive manner, and help students become more socially-conscious, compassionate, and engaged citizens.

It's a potentially life-saving experience for students, and in turn, "a great gift for teachers," says Dr. Sanderlin.

"I wish I had the WE Teachers program when I was a teacher because it provides the online training and resources teachers need to begin to grapple with these critical social issues that plague our students every day," she adds.

In addition to the WE Teachers curriculum, the program features a WE Teachers Award to honor educators who go above and beyond in their classrooms. At least 500 teachers will be recognized and each will receive a $500 Walgreens gift card, which is the average amount teachers spend out-of-pocket on supplies annually. Teachers can be nominated or apply themselves.

One of the major differences between women and men is that women are often judged based on their looks rather than their character or abilities.

"Men as well as women tend to establish the worth of individual women primarily by the way their body looks, research shows. We do not do this when we evaluate men," Naomi Ellemers Ph.D. wrote in Psychology Today.

Dr. Ellers believes that this tendency to judge a woman solely on her looks causes them to be seen as an object rather than a person.
